So, here’s the situation. I have a 20-year-old sister who has been, frankly, a very strange person since she was little. I’m not trying to sugarcoat anything here. Even back when we were kids, she used to get this weird thrill out of it when our parents blamed me for things she actually did. I just got used to it, and at the time, I didn't think it really shaped who I am. We just brushed it off as childhood stuff. But a few years ago, the real trouble started. She dealt with so much bullying at school that we had to move her to different classes because she just couldn't fit in anywhere. We did everything in our power to help her and make her feel comfortable in her own skin. Around that time, she started taking Pfizer and some sleeping pills that a psychologist in Washington, D.C. recommended. Things stabilized slightly, but then high school hit. Same story—bullying issues again. We moved her grades around, eventually transferring her to a different school entirely. Suddenly, everything changed. She became completely narcissistic. I figured, okay, it's just puberty, we can handle it. We put up with it for three years. By senior year, it turned into a total disaster. Our relationship deteriorated completely; the nicest thing she’d say to me was "You're stupid!" Her relationship with our parents was even worse. She would insult my dad in every way imaginable, and the worst part was when she’d stand right in front of him, screaming about how little he’s ever done for her. (And let me be clear: our parents have provided us with ABSOLUTELY EVERYTHING in life). She treated my mom even worse—it reached a point I don't even want to write down. Things calmed down briefly when she went back on the Pfizer.
Then, we find out Mom is sick. Multiple sclerosis. There was still a semblance of peace. Then, just a few months later, things took an even darker turn when Mom found a lump in her breast and had to undergo surgery. It was cancer. The fight began, and we all tried our best to stay positive and help however we could. Everyone except my sister. Out of nowhere, she gets even worse. She starts gaslighting Mom, telling her she’s the reason she has cancer, and she hammers away at her with that guilt every single day. Mom cries every day, and Dad is on the verge of a nervous breakdown. In the last month alone, I’ve had to beg Dad twice not to kick her out of the house. I know I’m wrong for doing that, but she's my sister. The situation won't settle down; she insults everyone, including our cat! (Yes, it sounds ridiculous), nothing is ever good enough for her, she thinks she's the only smart one, and she keeps piling guilt on Mom.
The breaking point happened yesterday. Since I have a job and my own income, Mom gave me a little gift, which she hasn't done in a long time. My sister absolutely lost it. Once again, the verbal abuse toward Mom and me started. Today, she’s giving us the cold shoulder, and she is entirely responsible for Mom's tears.
I want to go back to our relationship, which used to be good. Once. I remember one day talking to her calmly about relationships. I meant sexual ones, and I told her she shouldn't feel ashamed and that she had my support, suggesting she come to me for protection or advice if she didn't want to ask Mom, though I mentioned sex wasn't really my thing. She said she'd ask me about everything. Well, today I found out she performed oral sex on the son of our parents' close family friends. Who? My sister, apparently. I am in total shock.
To clarify that last part, we know the names of a couple of her friends, but we only know what two of them look like. She never brings anyone home, even though our parents are wonderful people. I always brought my friends over, including my boyfriend. That's normal to me. When she goes out into the city, she rarely says where she actually is, and she has spent New Year's Eve alone for the last three years. We essentially know nothing about her. She lives one life with us, and a completely different one outside. Please, help me.
Sorry for this long, messy post; I'm just feeling incredibly overwhelmed right now. Any advice is welcome...
It honestly blows my mind how much people are willing to overlook bad behavior just because of a blood relation. So what if she’s your sister? If she were a murderer, would that somehow make her actions okay in your eyes?
Why on earth would you shield and enable someone acting like this?
There has to be a line somewhere, whether it's a sister, a parent, a kid, or a spouse...
She clearly has issues, and by protecting her and catering to her every whim, you aren't helping her at all—let alone making life easier for yourselves. All this does is give her the impression that whatever she pulls, she'll be forgiven. She'll never respect you or listen to you this way.
She’s the last person who deserves pity here.
Your mother is dealing with health issues, but should you really have to put up with this?
Do it for her, if you won't do it for yourself.
If I were in your shoes, I’d lay down some serious ultimatums.
Therapy—so she can actually figure out what's wrong since she refuses to talk to you about it.
I don't know if she's working or in school... whatever, she needs to get a job.
Zero tolerance for toxic behavior. If she wants to be nasty during a conversation, fine, then there's nothing left to talk about.
Since she’s already eaten up so much of your time, I’d also set a deadline for when she actually needs to show some progress.
Set boundaries, establish rules, and actually stick to them.
For this to work, everyone in the family has to be on the same page. If she spots one weak link, she’ll exploit it and everything will go right back to how it was.
If there’s no change, or even a desire to change, I’d wish her the best and show her the door.
